Short text descriptions and speech bubbles combine with a graphic-novel format to present the stories of three WWI spies in this volume from the high/low Spy Story Graphics series (4 titles). A brief introduction to the Great War features a map and helps readers understand the nations affiliated with the Central and Allied powers. Successive chapters spotlight influential Allied spies: Louise de Bettignies, who set up a spy base known as the Alice Network in Lille, France; Richard B. Tinsley, a British secret agent working in the Netherlands for a group that became known as MI6; and Sylvanus Morley, an American archaeologist who gathered German intelligence in Mexico and Central America. A limited color palette reinforces the time period, while the expressive illustrations emphasize each spy's harrowing experiences.
